摘要
通过杯芳烃的酚羟基的直接烃基化反应,在杯芳烃的下缘引入2,3′-二甲基-4-氨基偶氮苯发色团,得到了一系列杯芳烃偶氮衍生物(n=4,6,8)a-c.研究了它们对碱金属,碱土金属及过渡金属等十种金属离子的萃取作用.结果表明此类杯芳烃偶氮衍生物对过渡金属离子有良好的选择性识别作用,其中空腔较大的杯[8]芳烃偶氮衍生物c的萃取效果尤为显著.
The complexing and extraction properties of three calix[ n] arene amidoazobenzene derivatives a-c modified（ n = 4, 6, 8）on the lower rim of ealix[ n] arene with 2, 3＇-dimethyl-4-ehloroaeeto- amidoazobenzene for alkali, alkali earth and transition metal cations were studied by means of atomic absorption methods. The results showed that ealix[ 8] arene amidoazobenzene derivative c had best extraction capacities.
